Exalt i-Series Installation and Management Guide
5000001 37
2007-04-15
L = Total transmission system losses of all elements between the
radio’s RF connector and the antenna’s RF connector (all cables,
connectors, lightning suppressors), in dB, as specified or
measured between 5250 and 5350 MHz
For the 5250–5350 MHz band, the maximum EIRP allowed for this device is 30dBm.
The maximum output power of the radio shall never exceed +13dBm.
The professional installer is responsible to ensure that RF output power is properly
adjusted so that it does not exceed the regulatory limit of these conditions.
Time Division Duplex (TDD) Factors
The i-Series radios are very dynamic, allowing the installer to optimize and control the
performance of the radio system for the intended application. The following parameters
must be carefully determined during the link engineering phase:
• Link distance
• Bandwidth
• TDD frame size
• Mode (modulation)
The setting of the above parameters determines the following performance factors:
• Number of supported T1/E1 channels
• Ethernet throughput
• System latency (delay)
Use the ExaltCalc calculator to determine optimum settings for the above parameters to
meet the needs of your application.
The following generalizations can be made with regards to these factors:
• The shorter the TDD frame size, the lower the latency
• The shorter the link distance, the lower the latency, the higher the throughput
• The longer the TDD frame size, the higher the throughput
• The higher the bandwidth, the higher the capacity
• The higher the mode, the higher the capacity
Note: Disable all T1/E1 ports if there are no T1/E1 interfaces
connected. This shifts all available throughput to the Ethernet interface.
Note: If a selected combination of the Link Distance, Frame Size,
Bandwidth, and Mode parameters cannot support all the desired T1 or E1
ports, the ports that cannot be supported are automatically disabled.
Priority is placed on the T1/E1 port number. That is, the first port to be
